Noise reduction apparatus for shift cable

Abstract

A noise reduction apparatus for a shift cable, may include a mounting socket that is fixed to a shift lever mounting bracket, with an inner cable of the shift cable therethrough, a cable connection pipe that has one side connected to a shift lever-sided end of an outer cable of the shift cable, and a housing connection pipe that has one end elastically-coupled to a shift lever-sided end of the cable connection pipe with a predetermined distance therebetween by a first antivibration member in a damper housing and the other end thereof elastically-connected to the shift lever mounting bracket by a second antivibration member in the mounting socket.

What is claimed is: 
     
       1. A noise reduction apparatus for a shift cable, comprising:
 a mounting socket that is fixed to a shift lever mounting bracket, with an inner cable of the shift cable therethrough; 
 a cable connection pipe that has one side connected to a shift lever-sided end of an outer cable of the shift cable; and 
 a housing connection pipe that has one end elastically-coupled to a shift lever-sided end of the cable connection pipe with a predetermined distance therebetween by a first antivibration member in a damper housing and the other end thereof elastically-connected to the shift lever mounting bracket by a second antivibration member in the mounting socket; 
 wherein the shift lever-sided end of the cable connection pipe has a flange having an increased diameter; 
 wherein the housing connection pipe has first and second flanges having an increased diameter at both the one end and the other end thereof respectively; 
 wherein the damper housing is formed to cover the flange of the cable connection pipe and the first flange of the housing connection pipe to prevent the flange of the cable connection pipe and the first flange of the housing connection pipe from opening; and 
 wherein the first antivibration member prevents direct contact among the damper housing, the flange of the cable connection pipe and the first flange of the housing connection pipe, and the second antivibration member prevents direct contact between the mounting bracket and the second flange of the housing connection pipe. 
 
     
     
       2. The noise reduction apparatus for the shift cable as defined in  claim 1 , wherein the mounting socket is formed to cover the second flange of the housing connection pipe to restrict relative motion of the second flange in a longitudinal direction of the shift cable with respect to the mounting socket. 
     
     
       3. The noise reduction apparatus for the shift cable as defined in  claim 2 , wherein the flange of the cable connection pipe and the first flange of the housing connection pipe in the damper housing have the same shape and are positioned to face one another; and
 wherein the one end and the other end of the housing connection pipe are formed in the same shape in symmetry. 
 
     
     
       4. The noise reduction apparatus for the shift cable as defined in  claim 1 , wherein the cable connection pipe further includes a spacer formed along an inner circumference thereof to receive the inner cable therein. 
     
     
       5. The noise reduction apparatus for the shift cable as defined in  claim 1 , wherein the housing connection pipe further includes a spacer formed along an inner circumference thereof to receive the inner cable therein. 
     
     
       6. A noise reduction apparatus for a shift cable, comprising:
 a mounting socket that is fixed to a shift lever mounting bracket, with an inner cable of the shift cable therethrough; 
 a cable connection pipe that has one side connected to a shift lever-sided end of an outer cable of the shift cable; and 
 a damper housing that has one side elastically coupled to a shift lever-sided end of the cable connection pipe by a first antivibration member therein and the other side thereof elastically coupled to the shift lever mounting bracket in the mounting socket by a second antivibration member, 
 wherein the damper housing has an integral flange having an increased diameter at the other end thereof which is disposed in the mounting socket while the one side thereof covers a flange formed in the shift lever-sided end of the cable connection pipe and elastically coupled thereto by the first antivibration in the damper housing, wherein the first antivibration member prevents direct contact between the flange of the cable connecting pipe and the damper housing; and 
 wherein the mounting socket is formed to cover the integral flange of the damper housing and elastically coupled thereto by the second antivibration to restrict relative motion of the integral flange in a longitudinal direction of the shift cable with respect to the mounting socket, wherein the second antivibration member prevents direct contact between the integral flange of the damper housing and the mounting socket. 
 
     
     
       7. The noise reduction apparatus for the shift cable as defined in  claim 6 , wherein the cable connection pipe further includes a spacer formed along an inner circumference thereof to receive the inner cable therein.
